Abstract

Multi-channel compressed analog-to-digital (ADC) samples along with compressed calibration data received from the radar unit are de-compressed on the centralized signal processing unit prior to calibration compensation and DC-offset removal. Time-domain samples on each antenna channel are processed into range-domain samples and range-Doppler samples using windowing and FFT operations. For each range-domain sample, angle-domain samples are generated by performing windowing and angle-domain FFT operation over antenna channels. Joint object detection is performed separately on de-compressed ADC samples, range-domain samples, range-Doppler samples, or range-angle samples to provide detection metrics and confidence levels for each detected object.
